tag_insight = "Kerberos is a network authentication system which allows clients and
  servers to authenticate to each other using symmetric encryption and a
  trusted third party, the Key Distribution Center (KDC).

  Multiple checksum validation flaws were discovered in the MIT Kerberos
  implementation. A remote attacker could use these flaws to tamper with
  certain Kerberos protocol packets and, possibly, bypass authentication
  mechanisms in certain configurations using Single-use Authentication
  Mechanisms. (CVE-2010-1323)
  
  Red Hat would like to thank the MIT Kerberos Team for reporting these
  issues.
  
  All krb5 users should upgrade to these updated packages, which contain a
  backported patch to correct these issues. After installing the updated
  packages, the krb5kdc daemon will be restarted automatically.";
